I use Spybot as an anti-spyware program
________
FREE VAPORIZER

NAV2008. Excellent, does'nt slows the system like Norton 360 or like the earlier versions. Also the virus definitions on the norton official site helps a lot.

I have used Grisoft - AVG free edition. It works well and isn't too complicated.

I have used AVG with great results. However it slowed down my laptop too much so I deleted it now. I usually install it when I suspect something.

its AVAST free edition for me... I've tried most of antivirus but in avast I stayed.

I used NOD32 anti-virus and I am happy with it.

I was fond of using the Symantec Antivirus but now a days I am one of the big fan for Nod. Its one of the best application you can use for removing the viruses from your PC.

You are definitely right. I used to changed every now and then my anti-virus. But when I installed NOD, I didn't click the uninstall button and continue to use it up to now. You must try it guys.. :)

I am using Symantec Antivirus which seems to be good one.

Whwn I use to use PC, I used Symantec/Norton like most people. Then, it became fat and slow. So I switched to BitDefender. It works really well. People who are running PCs, I still do recommend it.
